So Perfect could be Royal Ascot-bound after getting up in the dying strides to make a winning debut in the Tara Sires Irish EBF Fillies Maiden at Navan.
The Aidan O'Brien-trained daughter of Scat Daddy had plenty to do at the furling pole, but she responded well to Ryan Moore's drive once getting a clear run on the outside to put her head in front on the line.
The 4-1 shot collared Mater Matuta by a short head, with Silver Service three-quarters of a length away in third.
O'Brien said: "We're delighted with that for a first run. We were worried about the ground and experience, but she is obviously a very nice filly. She is a big, powerful filly.
"I'd say she is an Ascot filly and could run over five or six (furlongs). She could run at Naas (in the Listed Juvenile Fillies Sprint over six furlongs on May 20) for some more experience."
